Had my first day on them today. I am coming from quick entry bindings but dealing with the two straps wasn't that bad. The movement in them is very subtle but I did notice a difference in response. I may try out the soft bushings next time out just to see if they are more noticeable.

Edit: Thinking on them the only real things I might tweak are a hinge of some sort to get the ankle straps out of the way when strapping in, maybe another millimeter or two of travel and a slightly cushier ankle strap but they really are fun to ride.

Rode them with the soft bushings and enjoyed them a lot more. I am probably 215 in all my gear so the soft were really soft. The movement in them was that much more pronounced. I think with the blacks they would be almost imperceptible to regular bindings.Enjoying these more with each run. Gonna run them without the highback next week to see how that feels. I am wondering if Now might put out a bushing even softer than the whites, I would definitely like to try them if they did.

So I have 5 full days on them now. First day with the medium bushings, next three with the soft and the highbacks on and then today went with the soft and no highback. The conditions were probably the worst you could want for that set up, really icy and hardly any features open. I have to say it was still super fun. The binding responds just as well without the high back and I was riding them in a two year old pair of Northwave Freedoms that are a very soft boot.

Towards the end of the day as it iced up more I switched over to a pair of Salomon F22s and my Smoking Mailorder Bride with K2 Uprises. While the board is much damper than the Westmark I have the Nows on you could really feel the advantage in response that the Nows give. It was especially pronounced steering one footed off the lift. Part of it is the the Arbor is easier to twist but I had ridden it with the K2s and the difference is quite noticeable. As far as how they are holding up, mine still look new aside from the Now logo on my back footbed having fallen off.

Thanks for your input. I asked questions earlier in the thread regarding going highbackless and it seems no one rode it that way. With the king pin design it seems theoretically you don't really need highbacks.
